According to the package they came in, the light is considered warm. It doesn't list eh Kelvin rating. The best part is they fit in my regular medium sized desk lamps in the same socket I removed the incandescent 70W bulbs from. Can't wait o see if they make a difference in my monthly electric bill because I can replace about another 20 of them throughout the house. Hop this helps. Also box sys they have a 30 day guarantee.

These are 3000 kelvin color. If you do not understand that, please do yourself a favor and go to a local lighting store to see them in person. Any light that produces 3000 kelvin will look the same with varying degrees of intensity.And as others have said, they are not good for plants. You can buy LED growlights, but they are only good in that they use very little power. And it is probably better to get a HPS bulb and ballast than to even think of LEDs.

The threaded area is made of plastic so temperature is their main concern. LED's should be fine.

Maker replied me - it's in 5,000K. It's Kelvin btw. Still no words on lumens though...

The top-end (brightest) light is capped at 4500 lumens. On a Kelvin light scale it's a bluish-white light, which could be enough for your photography project. I've tried looking up a conversion scale, but those 2 units seem to be difficult to relate quantitatively, since it's not a bulb that you're measuring--high intensity LEDs instead. If you look up fluorescent bulbs, 4650 lumens delivers about 5000 Kelvin temperature light.

I don't know the answer, as I don't recall finding that info. I can tell you I've been running 8 LEDs and (5) 7 watt fixtures for about a year with no problems.

Absolutely not ..... it is a much warmer 2700K. For my taste, it is one of the nicest LED lights I have seen and I tried out a lot of them (CREE, Sylvania, Halo, Phillips, etc).

I googled what appears to be the answer in question, 3000 Kelvins. 500 K one way or the other, what are you trying to achieve, ambience. These aren't mood lights. These babies throw out great white bright light, and just the way I like it.

Its what you are referring to as harsh white. Its a very high color temperature, although I dont know the exact number, I could say its about like 6000 Kelvin LEDs. And the light output is very high, brighter than my 50 w halogens which it replaced.

Hi Ronnie, the lifespan of this bulb is estimated at 50,000 hours. This includes lumen depreciation and other factors. Most high quality LED bulbs are rated by Energy Star at 30,000 to 35,000. Thanks!

I have no idea. I will say this light favors the white side of the LED color spectrum more so than the 3000K advertised. I use it above our kitchen sink. Being that this light is super cheap, I'd give it a shot.

No way to tell. If there are no mechanical failures, the LEDs should work for at least 50 years! Nothing to wear out.

I do not know the exact lumen output.... But I would guess it to be around the 1800-2500 range. I basing that on how it compares to other LED lights I own with stated lumen ratings. I do not know The warranty length either, but LEDs in general are known for their long life, and I can say that the housing on these particular lights are very durable... The two units I purchased have endured constant salt water sprays, occasional contact with petroleum based liquids and frequent cleanings with a 4000 psi pressure washer. They have been left on continuously for several months without over heating. Highly recommended. P.s. These are installed on an oil rig in north Dakota. I do not know the exact lumen output....

No, unless you take the unit apart and conduct some DIY soldering and find a matching LED. However, LEDs have a general life expectancy of 50,000 hrs. If you use your lights for 10 hours a day, it should last 13.7 yrs. Of course it can lost longer.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

I don't know about -20, but they have a very high failure rate at 75. I've lost two lights out of six in the first few months of operation. LED wholesalers sent me new drivers, which had to be soldered into the units, but I'm extremely wary now of the lights
